Alexander and Anders

I have a step-son names Alexander. My husband has his heart set on naming our son Anders. While I really do like the name, I think it will be too similar to his brother's name. Alexander does not have a short-name yet; although I expect it will end up being Alex, it could possibly be Zander, even more like Anders than Alexander is.

As background, my husband is Swedish and we want a Swedish name for our son.
